Do I need to replace all switches and access points?
The answer depends on the models, firmware and intended controls. The assessment must distinguish equipment that meets the design, equipment that requires restrictions and equipment that needs replacing. Compatibility must be checked by function against the official matrix.
Can I start with guest Wi-Fi only?
Yes, that can be the project's initial scope. Even at this stage, it is important to validate isolation, the portal, duration, traceability and access termination. Expansion to corporate 802.1X is a subsequent architecture decision.
Is MAB enough to protect printers and IoT?
It should be treated as identification with limitations. The recommended design combines controlled registration, least privilege and exception tracking. Equipment capable of stronger authentication should be assessed for its use.
Does NAC replace a firewall or endpoint protection?
No. The project coordinates these controls. Admission and segmentation policies must coexist with traffic inspection, endpoint protection and incident response. Each layer must have its own function, owner and evidence.
Does the guest VLAN already guarantee isolation?
Acceptance testing must include tests between guests, internal networks and infrastructure services. The outcome depends on the rules and communication paths actually configured, including IPv6 where present.
Does having a valid certificate guarantee authorization?
The project must separate certificate validation from access permission. Identity, association with the device or user, authorization validity and any restrictions must inform the decision.
Does PacketFence require an agent on every device?
Network authentication mechanisms can use the system supplicant or MAC-based identification. Posture checks and provisioning have their own dependencies, which must be confirmed for each integration and operating system.
Does access continue when a server fails?
This must be demonstrated for the chosen architecture. Existing sessions, new authentications and the portal may behave differently. The pilot must include node and dependency failures, with an explicit contingency policy.
Can we retain the company's visual identity?
Yes, the portal provides documented customization mechanisms. The project must preserve accessibility, clear states, mobile compatibility and the platform's upgrade path.
Does PacketFence deliver LGPD compliance?
The project can contribute access controls and records. The organization must validate the purpose, data collected, retention and responsibilities with its privacy team. A portal or tool alone does not demonstrate compliance. ANPD guidance on information security.
How long does deployment take, and how much does it cost?
It depends on fleet compatibility, identity and PKI maturity, the number of flows, redundancy needs and operational scope. The initial assessment should turn these variables into stages, acceptance criteria and a proposal.
